How to choose children’s hearing aids
When the doctor tells the parents that “your child has hearing loss, it is recommended to matchChild hearing aidAt the time, I believe that many parents are very difficult to accept such a reality. They are unwilling to let their children wear eye-catching hearing aids and break into the tangled state of “matching and not matching.” However, after consulting the audiologists, parents are generally Understand an important issue – must face the reality, first compensate the child’s hearing is a big thing. Then enter the “select difficulty” state – what kind of good? With a general or with a valuable point Because I have never been exposed to hearing aids before, or have been overwhelmed by the overwhelming introduction of network products, or misled. In the article to help parents clarify several key points to choose hearing aids:
Degree of hearing loss
This is an important indicator that must be referenced. Just like we buy a pair of shoes for our children, we must first measure the length of the small ankles, and then refer to the size standard given by the manufacturer. The actual inner length of the shoes should be chosen to be a little longer than the actual foot length, because it is comfortable. You can wear it a little more, but too much is not suitable. It is not difficult to understand why there are so many hearing tests before the fitting. The audiologist should lock several hearing aids of appropriate power based on the results of the test, the degree of hearing loss. It is generally recommended to have an adjusted spatial power range. This is to prevent adequate hearing compensation through adjustment of the remaining space when the child’s hearing is fluctuating.
Hearing loss type
The classification of hearing loss is similar to true myopia, pseudomyopia and mixed myopia in myopia. This is based on the location of the hearing loss. The conductive lesion is in the external or middle ear transmission path. Generally consider the feasibility of using drugs or surgery. Secondly, consider whether it is suitable for fitting the hearing aid at this time. Whether it is suitable for air conduction hearing aids, etc. Sensorineural hearing loss lesions in the inner ear or auditory nerve position, this hearing loss can not improve hearing through drugs and surgery, the current effective intervention is mainly hearing aids. The mix is somewhere in between.
Hearing aid shape
The current mainstream brands are divided into the following categories:
Customized (in-ear; ear canal; deep ear canal).
I believe many people prefer deep ear canal because it is smaller and more concealed. However, for children, there are many limitations to choosing these shapes. For example, the limitation of physiological conditions is that the child’s ear canal is small, and the continuous development of the ear determines that the child is not suitable for such hearing aids.
So why are the behind-the-ear hearing aids more suitable for children? First of all, the power range of the ear-back machine is wider than that of the in-ear type; secondly, the ear hook design of the ear-back type (child series) is more in line with the physiological development characteristics of the child’s small ear, and is more docile; again, the back-ear type is acoustically Accessories – the ear mold sends the sound to the ear, the child’s ear develops once, the ear mold can be re-made, and the hearing aid is used. The ear mold is also easier to clean and not easy to block. These are the advantages that the ear does not have; finally, the ear type Some user-friendly design can help the child to be in a normal listening state, for example: there is no electric indicator light, wearing a good monitoring assistant, will not be played with a bad battery compartment door. These in-ear machines are currently not possible. If the child still has to passFMIf the wireless FM system is used for language training or class, then you must choose the back of the ear.RITEThe type of behind the ear is more suitable for children with certain operational ability and self-protection. Specifically, you can have an in-depth understanding with the audiologist.
Hearing aid life
A mobile phone is used for two or three years, not because it is broken, but because the performance of the machine has dropped. It turned out that typing was very quick, and then the screen response was slow, and it took a long time for it to be sent out. Especially affects the efficiency of communication. Everyday electronic products, whether systems or parts, are aging. Hearing aids also have a factory life test. If the environment is relatively humid, generally three years or so, the machine performance begins to decline; if the environment is relatively dry, generally five years or so, the machine performance begins to decline.
The above is the conclusion drawn in a specific test environment. In actual use, there are many variables in the child’s actual use. For example, an active nature will cause an accident, a large amount of sweat will be generated, and maintenance will not be careful enough to shorten the service life. We hope that everything will last forever, but the reality is very skinny, I heard that some people use it.10year? That is very rare. As a parent, in addition to doing daily and regular maintenance, you must also have a sense of advancement. Do not wait until the hearing aid is completely out of use, and consider upgrading. In the process of declining hearing aid performance, it is not a question of whether or not it can continue to be used. It is a question of whether the quality of listening has decreased. Especially for children, the key period of acquiring language and learning knowledge, the decline of that point is affected by accumulation.
